If you ran evolution all over again, would you get humans? How repeatable is #evolution? This video is sponsored by @BountyBrand. #biology #science #QPU #HygieneBeginswithBounty #BountyPartner Special thanks to Prof. Richard Lenski and team for showing me around the lab โ it is an honor to be able to witness and document such a historic science experiment. Thanks to Dr Zachary Blount for the help with research and setting up the competition time-lapse, Dr Nkrumah Grant for microscope images of the long-term line cells @NkrumahGrant Devin Lake, Kate Bellgowan, and Dr. Minako Izutsu for being part of this video.
